These 91-930 blades are 2.5" wide, not 3" wide like the Oregon 396-730 or the OEM M144196. The fit is good and they work fine, but time will tell if they last as long as the newer 396-730. The price of these blades is low enough, however, to ensure a great value even if they don't last as long. Shipping from SLE was very vast too. Overall, I am very pleased with the purchase.
